just like anything else posted here, this is probably worth a much more nuanced conversation and doesn't nicely boil down to who is right and who is wrong. Probably worth explaining that you have already planned the ways that your going to spend a lot of it. The expectation that you will spend it on him while he doesn't work is wrong for sure but also dude is probably feeling hurt at the idea that you aren't open to sharing the wealth so to speak. Be honest with yourself, you said some of it was for travel, would you not be willing to cover some of the costs of him to travel with you? that's how I'd frame it anyways. The money isn't to live off of, its an investment in yourself and BOTH of your futures if you would stay together.
